Look at the situation and find a way
Experts say that the first reason for the dark spot should be identified. Huang Xinhong, senior engineer of China Ceramic Industry Association, said that many manufacturers will add some dark flowers to the tiles. Consumers should distinguish whether this is intentionally designed by the manufacturer or accidentally. If it is indeed caused by the manufacturer's production mistakes, it is not solved by grinding. "The dark spots are on the glaze, and the sanding may still work, but under the glaze, it is difficult to solve the repair."
Can the floor tiles be partially replaced? Engineering experts say that this is also feasible, and the problematic floor tiles can be removed. If you just replace a few of the tiles, you may encounter the problem of chromatic aberration in different batches of tiles. Consumers can consider changing the tiles of other colors to match, as long as they are properly designed, they can also have a unique decorative effect.
It should be reminded that when the construction personnel change the floor tiles, care must be taken to deal with the boundary between the ground and the wall to avoid affecting the wall surface. Since the floor tiles are very difficult to dismantle, it is necessary to remove the bricks at the bottom of the wall at the same time. Under normal circumstances, the bricks at the bottom of the wall will be damaged in the process of dismantling. Experts recommend that consumers purchase new wall tiles of different sizes in advance.
Common disease analysis
During the use of ceramic tiles, many consumers reported that the tiles in their homes had dark spots or cracks. What are the reasons for these problems, is it a quality problem?
1. Cracks appear on the surface of the wall tile
The quality of the wall tiles is really poor, the flexural properties are very poor, and cracks may occur during use. However, this situation has appeared less. "Now the brand manufacturers will do quality inspection before leaving the factory." In addition, it is necessary to find problems in the project: First, there is no water conservation before the paving, resulting in brick surface due to cement mortar. The pulling force is cracked; the second may come from the base layer treatment such as waterproofing.
2. Water marks appear after the floor tiles are immersed in water, and will disappear by themselves after a period of time. Huang Xinhong said that this is generally seen on tiles that have been used for half a year, and rarely appear on new tiles. Because the tiles have been treated with anti-fouling and water-repellent treatment before leaving the factory, this layer of protective layer will wear out during use. "Although some bricks are very dense, there are still stomata in them." Over time, old tiles will see water seepage and water marks. "This is normal and not a quality problem." However, Huang Xinhong reminded that if the water infiltrated into the floor tiles, it will not leave traces after drying, and if the dirty water will leave scars.
3. The floor tiles turned into a numb face, and it took a while to seem more and more unclean.
The reason for this problem is the same as above, which is caused by aging and abrasion of the anti-fouling treatment layer of the tile. Some of the tiles were wiped off and some black spots appeared on the surface, which was due to cracks in the porcelain surface or some tiny potholes.
Experts say that such problems can only be considered as flaws in products, but they cannot simply say that they have quality problems. The standards required for different grades of tiles are also different. "If the condition of black spots is within the allowable range of the national standard of this grade, then it is still a good product."
Choosing to avoid trouble
To buy a hearty tile, consumers are better off picking it out. First, test the flatness of the tiles. It's easy to put the tiles together face to face to see if there are gaps between them. The smaller the gap, the flatter it is. “Uneven tiles will rise, this one can be seen at a glance.†In addition, if you choose bricks such as polished tiles, you can use the back drip to test the water absorption rate.
If the water droplets spread easily, the water absorption of the tile is high and the strength is not high. On the contrary, water droplets are difficult to absorb, indicating that the water absorption rate is small and the strength is high. If you are afraid of glazed tiles on the back side, it is best to soak the glazed tiles in the basin or the basin filled with ink. After a period of time, observe whether the tiles are obviously darker or more flowery, unchanged or change little. It is better.
Huang Xinhong introduced that the quality of ceramic tiles on the market is still good. Large manufacturers will do relatively strict quality inspection before leaving the factory, but it does not rule out some fish that are missing. The number of tiles purchased is generally large, and block inspection is not realistic. Consumers are advised to purchase big brand products. “Even if you encounter problems, it is relatively easy to solve.â€
